} may concern; Be ltkIlOWIl that I, FREDERICK E. FISHER- I ING, a citizen of the Umted States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Shade-Trimming Devices, of which the following is a specifica- My invention relates to a shade-trimming device; and the object of the invention is to enable shades to be evenly and neatly trimmed without removing them from the wooden rollers upon which they are ordinarily wound when sent from the factory.

A further object of the inventionis the provision of means for determining the exact point at which said shades are to be cut to produce a shade of a given width.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

Inthe accompanying drawings, Figure .1

j is a plan view of the shade-trimming device constructed in accordance with tion. Fig. 2 is a side elevation of said device witha portion thereof in section. Fig. 3 is an elevation of the shade-trimmer, and Fig. 4

my inven- "is an elevation of a portion of an upstanding lock or guide which is carried by a scale hereinafter described.

Like numerals designate corresponding parts in all of the figures of the drawings.

eferring to the drawings, the numeral 5 designates a base-plate. Mounted upon this base-plate are the bearing-standards 6 and 7. Journaled for rotation in these standards upon pintles, one of which is indicated at 8, are rollers 9. The standards 6 and 7 are recessed, as at 10 and 11, for the reception of a rolled shade 12, (see F'g. 2,) said shade being rotatably supported by the rollers 9. A longitudinal channel 13 is formed through the base 5 for the reception of a scale 14. This scale 14 is provided with ribs 15, which engage grooves 16, formed in the wall of the channel 13, by virtue of which construction the scale 14 is slidably mounted with relation to the base 5.

At its outer-end the scale 14 carries an upstanding block 1.7. This block is recessed, as at 18, said recess being faced by a curved metallic plate 19, this plate 19 and a wall 20 of the block 17, which. lies in the rear thereof, being adapted to receive one of the pintles 21 of the shade-roller 22. A plate 23, which is secured by screws 24 to the base 5, has

threaded therein a set screw 25, which is adapted to clamp the scale 14 in anyof its adjusted positions.

Pivoted at 26 to the bearing-standard 7 is a knife 27. This knife is provided with a handle 28 and carries a removable cuttingblade 29, which is secured to the knife proper by screws 30. The knife 27 travels in a guide 31. A plate 32 is vertically movable in this guide and is adapted to be clamped in any adjusted. position by ascrew 33, said screw bearing near one side of the guide 31 and being adapted to draw said plate up against the other side of said guide. This plate 32 forms a stop to limit the movement of the knife. A wire 34 is partially embedded in the standard 7 and serves to prevent the knife from scraping against said standard.

A handle 35 may be secured. to the base, if desired, to enable the device to be readily moved fromplace to place. An upstanding flanged boss 36 has a' central opening 37 formed therein, said boss being carried bythe base 5. When it is desired to shorten the shade-roller upon which the shade is wound, the pintle-carrying plate 38 is removed from the end of the shade-roller 22 and a suflicient portion of the roller is cut off with a saw. It is now necessary to drive the pintle carried by the plate 38, and which is of the usual and well-known construction, back into the shade-roller. It is injurious to the pintle 21, which is secured to the usual winding-spring of the roller, if said pintle be rested against a flat surface while the pintle at the opposite end of the roller is being driven into position. The opening 37 of the lug 36 is adapted to receive the pintle 21, by virtue of which construction the end of the shade-roller 22 adj acent the pintle 21 rests upon the top of the boss 36. 'The pintle carried by the plate 38 may now be driven into the opposite end of the roller withoutv injuring the pintle 21.

The operation of trimming a shade is as follows: If it be desired to cut off a shade to a length of twenty-five inches, for instance, the rolled shade is tratedin Fig. 2, with its pintle 21 resting in the recessed portion of the plate 19. If the gage now be moved until the graduation thereof indicated by the numeral 25 registers with the edge of theplate 23, the shade will be in proper position for cutting. The operator now rests one hand upon the rolled shade and with the other hand presses down upon the handle 28. This forces the knife or the placed in the position illusi -scrlbed are well "adapted to serve the :pur-
